CXCL1 induces the recruitment of neutrophils into the HCC tumor niche [147]; these cells secrete CCL2 and C-C motif ligand 17 (CCL17, thymus and activation-regulated chemokine (TARC)), which induce the recruitment of monocytes and Treg, respectively [149]. The gene discussed is CXCL1; the disease is neoplasm.
